Make seabios linkable with lld

[SeaBIOS] [PATCH v4 0/4] Make seabios linkable with lld

Posted by Fangrui Song via SeaBIOS 3 years, 7 months ago

Another try after
https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/KBHQU4OLW2THG5Q5F5X7EWTQDJHKNVYC/

The only change is the removal of `Makefile: Change ET_EXEC to ET_REL so that lld can link bios.bin.elf`
since 699a4e5d6919cc8eae5342443025ceb6909dc276
("ldnoexec: Add script to remove ET_EXEC flag from intermediate build objects")
has done the same thing.

For your convenience, the patch series is available on https://github.com/MaskRay/seabios/tree/lld

Re-sending. I posted this 3 days but got bounced.
I have now ensured there is my email address record on 
(previously not) https://mail.coreboot.org/postorius/lists/seabios.seabios.org/
as well as https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/

Fangrui Song (4):
  romlayout.S: Add missing SHF_ALLOC flag to .fixedaddr.\addr
  Make rom16.o linkable with lld
  romlayout32flag.lds: Use `. +=` instead of `. =`
  test-build.sh: Delete unneeded LD capability test

Hello all,

FreeBSD ports developer here.  Is there anything we can do to help get
this series of patches evaluated?

Thanks,

Joe

Can you elaborate on the part of the series that you need and why it
is needed?

This changeset has a long history and there is little desire to
revisit it.

Hello,

I don't understand all the constraints and history, but it would be nice
to be able to build SeaBIOS on FreeBSD with our in-tree tools.  The
differences between LLVM objdump and GNU objdump means that swapping in
LLVM objdump is not straightforward.
